Question

Last year there were 20,404 fans at an all-star game. This year there were 4,876 more fans. How do you estimate the percent increase?

Answer 1

See a solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as `x/100`.

Therefore the problem can be written and solve for `x` as:

`x/100 = 4876/20404`

`color(red)(100) xx x/100 = color(red)(100) xx 4876/20404`

`cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = 487600/20404`

`x = 23.9`

There was a 23.9% increase (rounded to the nearest tenth) in attendance.
